I was looking at the definition of visits in the Advan FAQ, which states that a single device can only contribute to visits once per day. How does that work ith the visits by each hour field?

I see a large number of POIs that had an enormous and usually permanent drop in visits/visitors starting in June 2023. This drop is especially prominent in NYC. I can't find any explanation for this.

Hello, I am working with Advan data and looking for specific data for a POI. However, it is missing and I cannot triangulate it with lat/long data either.

I'd like some clarification around discrepancies in placekeys between Advan and Safegraph.

Hello,

I have a couple of questions about the Advan Monthly Patterns - Home Panel Summary.

Using the Weekly Patterns - Foot Traffic - Full Historical Data, I noticed that several rows have identical values for raw_visit_count, raw_visitor_count, and origin_home_cbg, as well as the visitor count within origin_home_cbg, even though these locations have different placekey values. I checked their parent_placekey, and while some of them share the same parent, others do not. Additionally, I examined whether all child_placekey values under the same parent_placekey had matching raw_visit_count, raw_visitor_count, and origin_home_cbg, but that wasn't always the case.

We are researching human mobility and have calculated the visitor rate for each CBG in Erie County using the formula: Visitor Rate = Visitors / Number of Devices.

I noticed data that I thought was missing from the Advan datasets. Heads up if you have the same issue -- the GEO IDs are connected to 2010 Census Block Groups, not 2020. Glad I solved this, hope this helps someone else!

I'm trying to understand the representativeness of Advan data. What percentage of U.S. cellphones does it capture at a given point in time? Does this coverage percentage fluctuate over time, and if so, what factors influence these changes?
